Abstract

The invention belongs to the field of lead-acid storage batteries and particularly relates to a process for quickly curing and drying a negative electrode plate. The process at least comprises the following program steps of (1) a curing constant-temperature high-humidity maintaining stage, (2) a curing heating constant-speed dehumidifying stage, (3) a curing heating rapid dehumidifying stage, (4)a drying heating rapid dehumidifying stage, (5) a drying high-temperature rapid enhancing stage and (6) a drying cooling rapid strength stabilizing stage. According to the green polar plate cured anddried according to the process, the content of basic lead carbonate of the green polar plate is increased, the falling strength of the green polar plate is further improved, lead plaster looseness isreduced after falling, and the floating powder amount on a surface of the green polar plate is reduced, improvement of the strength of the green plate reduces a reject ratio of subsequent slicing andwrapping of the green plate. The process is advantaged in that the floating powder amount is small, lead powder flying dust in the subsequent polar plate production process is reduced, and environmental pollution is reduced, and the rapid curing and drying process can reduce the use amount of steam and electricity in the process, reduce curing and drying energy consumption and reduce manufacturingcost.

Description

technical field [0001] The invention belongs to the field of lead-acid storage batteries, and in particular relates to a process for rapid curing and drying of negative raw plates. Background technique [0002] Lead-acid batteries are widely used because of their stable performance and high cost performance. Especially, the market demand for electric bicycle batteries is increasing, but the price is getting lower and lower, which puts pressure on the production cost of manufacturers. The manufacture of negative raw plates is indispensable in the battery manufacturing process. Curing and drying in the manufacturing process of negative raw plates is one of the important links in the process. The quality of the curing and drying directly affects the strength of the green plates and the strength of the battery. performance. During the curing and drying process, the raw plate is cured and dried in the curing room, which is in a closed state, and the appearance change of the gree...
